To combat this new wave of wrongdoing, the Recently Armed Police of Tokyo was established in hopes of hunting down criminals with lethal force.

Amawa Hibiki is a young man just out of college, with an education to be an athletics teacher. He's been having a hard time finding a job since he graduated, so all his money has gone towards living expenses. When his landlady demands his first payment to live in her living establishment upfront, he heads to the local middle school to get hired as a teacher. However, the principal refuses to hire him without hesitation. She will not hire men as teachers and makes it clear that she hates all men, saying they put no love into their passions and work. Amawa does not give up and with the help of his landlady, he crossdresses as a woman without a second thought, and gets hired, so he can earn money and also prove the principal wrong. Now, he has to keep his real gender a secret, and avoid strange situations, including the affections of his students (from both genders).

The story takes place in Tokyo Butei High School, a special school where armed detectives—"Butei"—are trained to use weapons. Kinji Tooyama is a second-year-student who has a special ability, but he keeps it a secret to maintain an ordinary, peaceful life; however, when he gets caught in a bombing on the way to school, he encounters H. Aria Kanzaki, the most powerful S-Rank Butei student in Assault Studies.
